It is true that "the battery is not broken but charged".The battery charging performance plays an important role in the service life and performance of the battery, so it is necessary to pay attention to the way of charging the electric scooter. According to the situation of the majority of users, the most ideal can choose to charge the battery with the discharge depth of 50%-70%, charge the best, so that the battery life can achieve the best effect.At the same time, the effect of temperature on charging is considerable.In the hot season, the battery has the problem of charging.Should try to reduce the temperature of the battery, ensure good heat dissipation, avoid sun exposure after charging, the sun exposure can make the battery temperature increases, all kinds of battery increase activity of active material, affect the service life of the battery., by contrast, under the condition of low temperature, battery charging accept ability difference, the problem of insufficient charge, in this case, must improve the extended charging voltage and charging time, and insulation anti-freezing measures are taken, so that to ensure adequate electricity, prolong the service life of the battery.
